SPLINT-DBYING MEANS FOR MATCH-MACHINES.

Application filed June 10, 1913. Serial No. 772,776.

To all whom it may concern:

Be it known that I, JOSEPH C. DONNELLY, a citizen of the United States, and resident of Barberton, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Splint-Drying Means for Match-Machines, of which the following is a specification.

This invention relates to splint-drying means for match machines, having reference more especially to continuous machines wherein an endless carrier receives the splints row by row and transports them through the match making path, including a bath of impregnating material adapted to render the splints non-glowing after the same, as finished matches, have been ignited and the flame extinguished.

The ob ect of my invention is to provide for such machines a drying structure into and through which the wet splints, after they have been subjected to the bath of im pregnating material, are carried and thereby effectually dried in a relatively short space of time.

An important feature of my invention resides in the provision of a drying chamber chamber.

of such construction that the vapors arising therein from the splints and .the air introduced to the chamber for the drying. of the splints are discharged therefrom at different points in the travel of the splints, and thus the air, as rapidly as it becomes charged with moisture, is removed from the path of the splints and the latter in consequence are progressively subjected to the efficient drying action of the infiowing air.

In the form of embodiment of my invention herein illustrated the structure, as gen erally' stated, comprises a drving chamber through which the splint carrier is directed:

an air-egress conduit in communication with said chamber at difierent points in the path of travel of the carrier; a heater arranged within the chamber, and means whereby a current of air is supplied to the The invention also comprehends various novel features of construction and arrangements of parts whereby advantages are secured, as will be hereinafter described and claimed. In the drawings Figure 1.1sa longitudinal vertical sectlon of the drier, showln the impregnation? tank and a portion v0 the line 5-5 of Fig. 3.

A designates a portion of an endless carrier by means of which rows. of splints are transported in spaced relation to each other through the match making path. This carrier, in the form illustrated, comprises fleXibly-connected plates provided with rows of perforations to receive and hold the ends of the splints; the adjacent edges of successive plates being slightly separated or spaced (as indicated at a) to. permit the requisite flexure of the chain of plates'without liability of the end rows of splints of adjoining plates contacting with each other.

B designates a tank in which impregnating liquid is contained, which tank is suitably supported beneath the path of the carrier. The track for this carrier is appropriately constructed (as at a) to effect the vertical movement of the traveling plates or sections of the carrier in respect to the top of the tank after the carrier leaves the splint-inserting station of the match machine, and thus the splints during their progress are periodically dipped into and raised from the liquid contents of the tank in order'to effect the requisite impregnation of the splints.

The splint-drying structure through which travels the carrier with its load of wet impregnated splints, after leavin the tank B includes an inverted U-shaped rame 10 provided at intervals throughout its length with transverse openings 1L The carrier is impelled through the interior of I wall of the frame. This wall is provided with suitably spacedways 16 for the passage provided. The casing, in the present instance, comprises two side plates 17, an inverted U-shaped covering 18 and a bottom plate 19, the whole being bolted or otherwise tightly secured to the frame 10. The covering is adequately spaced from the internal frame to provide an intervening conduit 20 which merges with an outlet pipe 21 at the top of the casing, and the bottom plate is provided with a central opening which communicates with a depending intake pipe 22. Within this pipe is mounted a fan 23, the shaft of which, having its bear ings in brackets 24 bolted to the pipe 22, is provided with a pulley 25 which is driven from a suitable source of power, whereby a constant current of air can be supplied to the drying chamber. Any other appropriate means for establishing a-fiow of airto-the drying chamber may be substituted for that just described.

Arranged withinthe drying chamber are several heat radiators 26, comprising-in the present instance batteries or tiers of circulatory steam pipe systems, the pipes of which are preferably arranged in staggered relation to each other as shown. The radiators rest upon supporting bars 27 secured to the side plates of the casing, and each'bat tery of pipes is provided with a valve 28 (Fig. 3) for'regulating the admission of steam thereto; whereby any or all of the batteries of radiatorscan be rendered active or idle as requirements may demand;

' By the above-described construction it will be seen that a constant current of air is established within the drying chamber i be thereby effectually heated, the pipes by their staggered arrangement effecting an extensive heating and diffusion of the ascending air; and that as the carrier, with its load of impregnated splints, enters and passes in its extended course through the chamber, the splints are subjected tothe efiicient drying action of'the air. It will also be seen that the vapors arising from the moisture in the splints,"as well as the moisture charged air, pass directly into the conduit by way of the gaps in the carrier and the differently-disposed vents or openings in the frame, escaping thence through the outlet 21. Consequently the splints, as they progress through the drying chamber from the inlet 29. to the exit 30 thereof, are not exposed to the prolonged action of the vapor and the moisture laden air, but inflead they are subjected tothe immediate and eflicient dryingefi'ect of the heat and air from the extensive radiating surfaces presented by in the respective plates; and access to such plates is had through openings'in the walls of the covering, 18, which openings are closed by. removable plates 34 suitably secured to the said walls, as by'the thumb screws 35. T

In addition to the spaced openings 11 in the frame 10, communication is also preferably provided at intervals between the drying chamber and the conduit, by means of openings 36 and ducts 37 in the flanged edges tf said frame. These openings 36 can aiso be closed or opened more or less, as need may require, by means of plates 38 which are adjustably' secured to the frame 10, by cap screws 39 passing through horizontal slots 40 in said plates 38. As a means to deflect the heated air to and among the traveling splints preparatory to its escape to the conduit, inwardly-extending plates il are preferably secured at intervals to the flanged ends of the frame so as to lie adj acent the path of the splints in the carrier.

It is to be understood that I do not limit my invention to the exact details of con- 'Struction shown and described, as the structure may be variously modified" without departure from my invention.
